Registering air conditioning settings to electronic keys (vehicles with a smart
entry & start system)
Unlocking the vehicle using an electronic key and turning the power switch to
ON mode will recall that key’s registered air conditioning settings.
When the power switch is turned off, the current air conditioning settings will
automatically be registered to the electronic key that was used to unlock the
vehicle.
The system may not operate correctly if more than one electronic key is in the
vicinity or if the smart entry & start system is used to unlock a passenger door.
Settings for the electronic key and the corresponding door can be changed.
Contact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional.
Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and the
ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow
immediately after the “AUTO” button is pressed.
Fogging up of the windows
The windows will easily fog up when the humidity in the vehicle is high. Press-
ing “A/C” button on will dehumidify the air from the outlets and defog the
windshield effectively.
If you turn “A/C” off, the windows may fog up more easily.
The windows may fog up if the recirculated air mode is used.
Windshield fog detection function (if equipped)
When automatic mode is set, the humidity sensor (P. 458) detects fog on the
windshield and controls the air conditioning system to prevent fog.
Outside/recirculated air mode
When driving on dusty roads such as tunnels or in heavy traffic, set
to the recirculated air mode. This is effective in preventing out-
side air from entering the vehicle interior. During cooling operation, setting the
recirculated air mode will also cool the vehicle interior effectively.
Outside/recirculated air mode may automatically switch depending on the tem-
perature setting or the inside temperature.

Interior features
When the outside temperature is low
The dehumidification function may not operate even when “A/C” is pressed.
Operation of the air conditioning system in Eco drive mode
In the Eco drive mode, the air conditioning system is controlled as follows to
prioritize fuel efficiency
• Engine speed and compressor operation controlled to restrict heating/cooling
capacity
• Fan speed restricted when automatic mode is selected
To improve air conditioning performance, perform the following operations
• Adjust the fan speed
• Turn off Eco drive mode
• Customize the air conditioning control of Eco drive mode. (P. 658)
Ventilation and air conditioning odors
To let fresh air in, set the air conditioning system to the outside air mode.
During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning system. This may then cause odor to be
emitted from the vents.
To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air mode
prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time
immediately after the air conditioning system is started in automatic mode.
Air conditioning filter
P. 527
Customization
Settings (e.g. A/C automatic mode switch operation) can be changed.
(Customizable features: P. 650)

To prevent the windshield from fogging up
Do not use during cool air operation in extremely humid weather. The
difference between the temperature of the outside air and that of the wind-
shield can cause the outer surface of the windshield to fog up, blocking your
vision.
To prevent burns
Do not touch the rear view mirror surfaces when the outside rear view mirror
defoggers are on.
Do not touch the glass at lower part of the windshield or to the side of the
front pillars when the windshield wiper de-icer is on. (vehicles with wind-
shield wiper de-icer)
NOTICE
Humidity sensor (if equipped)
To prevent 12-volt battery discharge
Do not leave the air conditioning system on longer than necessary when the
hybrid system is off.
Do not place anything on the instrument
panel which may cover the air outlets.
Otherwise, air flow may be obstructed,
preventing the windshield defoggers from
defogging.
In order to detect fog on the windshield, a
sensor which monitors the temperature of
the windshield, the surround humidity, etc.
is installed. (P. 456)
Follow these points to avoid damaging the
sensor:
Do not disassemble the sensor
Do not spray the glass cleaner on the sen-
sor or subject it to strong impacts
Do not stick anything on the sensor
